Syntax

what
what folderName
s = what(___)

Description

what lists the path for the current folder and all the MATLAB® relevant files and folders in the current folder. Such files and folders include MATLAB program files (.m and .mlx), MAT files, Simulink® model files (.mdl and .slx), MEX files, MATLAB app files (.mlapp), and P-code files, as well as all class and namespace folders.

what folderName lists path, file, and folder information for folderName. You do not need to specify the @ or + symbol for class and namespace folders. For example, what table lists the MATLAB files and folders in toolbox/matlab/datatypes/@table.

example

s = what(___) returns the results in a structure array. You can use this syntax with any of the input argument combinations in the previous syntaxes.

Input Arguments

collapse all

Name of folder, specified as a character vector or string scalar.

For a local folder, you do not need to specify the full path of the folder. Instead, you can specify a relative partial path. For example, what strfun and what matlab/strfun both list the MATLAB files in toolbox/matlab/strfun. However, if the folder is at a remote location, then folderName must contain a full path specified as a uniform resource locator (URL). For more information, see Work with Remote Data.

The case sensitivity of folderName is determined by your file system. In general, Windows® and Mac systems are case insensitive and therefore, what returns results for all case variations of folderName. For example, suppose the folder c:\mycode contains the file myfile.m on a Windows file system. what successfully locates the folder even if you specify a different case.

what MYCodE
MATLAB Code files in folder c:\mycode
myfile

On Linux® systems, which are generally case sensitive, what returns zero results.
